Beacon Dome

Beacon Dome (

86°8′S 146°25′W / 86.133°S 146.417°W / -86.133; -146.417Coordinates: 86°8′S 146°25′W / 86.133°S 146.417°W / -86.133; -146.417) is a large dome-like mountain in Antarctica. It is 3,010 metres (9,880 ft) high, and stands at the head of Griffith Glacier along the Watson Escarpment. It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1960–64, and was so named by the New Zealand Geological Survey Antarctic Expedition (1969–70) because the mountain is composed of a granite basement with horizontally layered rocks of the Beacon Supergroup above.
